A call towards disarmament of the Kurdistan Workers' Party, or the PKK, marks the realization of a key expectation of the Turkish government but what matters is implementation, said Turkish President Recep Tayyip Erdogan on Saturday.

"It is a call that began with the democratic process, with this national unity and brotherhood project, which now continues with the solution process," Erdogan said in Istanbul ahead of his departure for Saudi Arabia for official talks.
